【摘要】 对20MN自由锻造油压机同步平衡控制系统进行了仿真研究,利用AMESim?和Adams仿真软件,分别建立同步平衡液压控制系统模型和活动横梁运动模型,并进行联合仿真,通过优化PID参数,使系统在不同负载干扰下均能具有较好的动静态特性。仿真结果表明,同步平衡控制系统能够有效补偿工件锻造偏心导致活动横梁四角的同步误差,同时在上升时间、调整时间、稳态精度方面均有较满意的效果,为实际系统的设计和调试提供了理论依据。更多还原

【Abstract】 The simulation of synchronism-balancing hydraulic system of 20MN free forging hydraulic press was done in this paper.The model of hydraulic system was founded by AMESim?,and the kinetic model of moving beam was founded by Adams.Then the technologies of co-simulation were used.By optimizing the parameters of PID,the system has satisfyingly dynamic and static characteristics under different load disturbance.Simulation results show that the synchronism-balancing hydraulic system can effectively compensate the synchronous error of moving beam corners which was caused by forging eccentricity,and the system also has satisfying rising time、settling time and static accuracy.These results offer the theory basis for the design and debugging of actual system.更多还原
